Workpiece deformation and cracking are common and troublesome problems in metal heat treatment processing after quenching. These defects will directly increase product rejection rate, cause raw material waste and delay production delivery. Many manufacturers adopt traditional tempering furnaces for post-quenching treatment, but the improvement is limited. Traditional equipment cannot completely eliminate residual stress, resulting in unstable workpiece quality. In contrast, induction heating tempering equipment can effectively solve these typical production pain points.
The fundamental cause of cracking and deformation is the uneven residual stress inside the workpiece after quenching. Traditional tempering furnaces feature large temperature difference and uneven heating, which make it impossible to release internal stress evenly and thoroughly. Adopting the electromagnetic internal heating principle, induction heating tempering equipment realizes uniform heating and precise temperature holding on the whole workpiece or designated area. It promotes uniform transformation of the internal metal structure and thoroughly releases residual quenching stress, fundamentally reducing the probability of deformation and cracking. With accurate temperature control, the equipment avoids new stress damage during heating and ensures stable workpiece dimension.
Compared with traditional equipment, this tempering solution delivers higher processing consistency and unified mechanical performance for mass-produced workpieces. It is applicable to both heavy industrial workpieces and small precision parts. Through customized tempering processes, the Induction Heating Tempering Equipment stabilizes workpiece hardness and toughness, effectively preventing deformation and cracking during long-term service. It is a reliable processing device to solve heat treatment defects of metal workpieces.
